Ron:
My research indicatesx that RCB initially enlisted in E/7 MISS as 1 SGT 4 May 61, and was subsequently promoted to 1 LT (not to CAPT). At the reorganization of the army in April 1862 he was not reelected and was dropped from the rolls.
He first appears on the rolls of Company C/Hampton Legion Infantry on the Mar-Apr 1863 roll as present enlisted at Columbia 1 Apr 63. Except for one company of the Legion, the rolls do not indicate who enlisted and who was conscripted; but as of 1 Apr 63 the Legion was on the Blackwater River in southeast Virginia, and men who apparently volunteered are shown to havew enlisted there. I strongly supect he was conscripted at Columbia, the location of the State Conscript Camp, and assigned to the Legion, as were a number of other men from the Pee Dee region during this time.
I am not looking at the entries in the Compiled Service Records (CSR) at this time, but my recolleciton is that the enlistee was described on by his first initial, "R. Bethea." He apprears on the subsequent rolls of the Legion as present through Oct 63, the last existant roll for the company until Aug-Sep 64. The Sep-Oct roll was apprarently prepared sometime in January 1864, after Jan 17, and in all probability reflects his status at that time, not the end of October.
